The Unicel 5CH-352 is a premium replacement filter cartridge built specifically for Marquis spa systems, delivering 35 square feet of effective filtration surface area. Featuring 151 precision-formed pleats of industrial-grade Reemay polyester media, this cartridge traps particulates as fine as approximately 20 microns to keep your spa water immaculately clean. A sturdy 2-inch male-threaded (MPT) base connection paired with a molded bar-top handle ensures secure seating and effortless cartridge changes. The 100% polyester construction stands up to repeated chemical exposure and cleaning cycles, providing spa owners with dependable, extended-life water purification they can count on season after season.
